TIRE-RIM.

Specification of Letters laten'ti,A

Patented Nov. 5, 1912.

Application filed September 21, 1911. '.Serial No. 650,487.

Tool! whom 'it may concern: Be 1t known that I, Jaains I).

ay citizen of the United States, and a resident of Kansas City, in thecounty of Jacksonl and State of il'l'issouri, have made certain new anduseful improvements in Tire-Rims, of which the following is aspecification.

My inv ntion relates to improvements in tire rims for automobiles orother similarv vehicles and it consists in the combinations,constructions and arrangements herein described and claimed.

An object of my invention is to provide a rim which will be ofrelatively light weight and one which will be strong, and which `willremain securely place.

A further ob]ect of my invention 1s to -niake a divisible rim inwhich'each'lialf is of the same size and strength.

A further object of my invention is to provide a divisible demountablerim having relatively few4 parts, and being therefore cheap tomanufacture.

Other objects and-advantages will appear in the following specificationand the novel features of the device will be particularly pointed out inthe appended el aims.

My invention is illustrated in the accompanying drawings in which-Figure 1 is a side viewof a tire rim and lock ring for the latter, Fig.2 is an enlarged section through the portion ofthe rim and locking ring,Fig. 3 is a transverse section through the device, Fig. 4: is aperspective view showing the securing lugs carried by the rimy sections,Fig. 5 is a perspective view showing the end of the spring locking ring,and Fig. 6 is a. section. along the line4 6-6 of Fig. 3.l ,Y l

In carrying' out my invention, I provide a felly l, which is providedwith a rim 2 having a flange 2* on one side thereof. At intervals aroundthe felly I provide transverse bores for the .reception of bolts 3.These bolts are `provided with heads 3b of the shape shown in Fig. 3arranged to enV gage the flanges 2. The opposite end of the bolt isthreaded as shown at 3 to lreceive a nut 4. Between. the nut and thefelly I provide a wedge shaped lug 5 like that shown in Fig. 3. l

The dividedhrim portions are shown at 6 and 7. These are provided withoverlapping 'portions as shown at, 8, and each sec tion 1s provided witha groove 9 arranged..l

to receive one of the flanges 10a of' a spring ANDERSON, p

- The spring expansion ring beveled and one end being expansion ring 10(see Fig. 5). The rim sections G andi 7 are provided with lugs 1l` and'l1A enit-their inner sides in which are disposed y Figs. 2 and. di)these bolts being norlnally extended by means of a spring 13 and beingarranged to lbe"'retracted by means of a laterallyextending pin 14.

`afpairof movable bolts l2 (see 60 In assembling the rim .the parts t5and' 7 65 are placed together so that the overlappingl edges 8 havetheposition-shownin Fig. 3. 10 is then placed 1n the position shown in Fig.l, the flangesV l0'L1 entering the slots 9 in the rim sections, and theend of the expansion ring l0 resting en the lugs 11 and 11 as shown inFig. 1. The spring ring is then forced into the position shown in Fig.2, the pins 14; being pulled inw ard] y spring ring to enter behind thebeveled edges of the lug 12 as clearly shown in Fig. 9 On releasing thepins 14, the bolts 12 will enter the slots 10b, thereby securely lockingthe rim sections together. The rim 80 thus forinedfis placed. on thewheel and the rim section 7 is brought into engagement'.I with theflange 2X. The Wedge plate 5 is then placed on the bolt 3 and the nut 4.is screwed up tight. The wedge being curved on itsV upper edge tends toforce therim against the opposite flange 2X and also towedge the rimtightly upon the felly band, thus preventing any chance of the rimbecoming detached from the felly.

It will be seen that the device is comparatively simple in its nature,and yet the parts are securely held in place.

In removing the rim, it is only necessary lto take oit' the nut et,remove the plate 5, slip off the rim, pull back the extensions 14 whenthe spring ring maybe easily taken out and the two parts of the rimsection will fall apart.

I claim:

1. The combination of a'pair of rim secf tions, each section beingprovided with a curved outer flange and a portionv adapted to overlapthe other seetiomsaid. rim sections 'being each provided with acircumferential| groove on its innerv sideadjacent to and parallel withsaid overlapping portions, a splitA spring locking ring having a pair offlanges arranged toenter the grooves in said rim members, the ends ofsaid ring being .provided with' sockets, a lug carried by each of saidrim so as to permit the end of the members,

-.spring ring memb each of said lngs having its ends beveled to providerecesses for thel beveled ends of said spring ring', and a springpressed bolt slidably carried by .each lug and arranged to enter asocket inthe end of the er.` 2. The combination Witha pair of--abuttingrim sections .each having a groove on its inner side parallel tothe-abutting portions, of a split 'locking ring having .its ends beveledand being provided with ianges arranged to enter said4 grooves, one endlof being; provided withv said' locking ring sockets, a lug carried byeach of said rim sections, said' lugs .bem

thebeveledends of sai l'spring ring, and a v movable locking member*carriedby each .l -lng and arranged toenter'a socket in the end of saidsplitring for locking the ring in position.

-3. The com ination with apair of vabutting rim sections each having agroove on its beveled to receivel -each lug for locking the ring inposition.

, 4. The 'combination with a'pair of abutting rim sections each having agroove on its -inner side' parallel to the abutting portions, cfa's'plitjlocking ring having its vends beveled'and being provided withflangesarranged to enter said grooves, and an integral lug lcarried byeach of said rim sections.f eachof -said lugs being beveled to receivethel beveled ends of saidsplit ring..
